The Company publicly expresses its gratitude to Mr. Mario Leão for his valuable contributions to Santander Brasil and its stakeholders over the last eleven years in which he has worked at the Company, whether as Chief Executive Officer and Member of the Board of Directors, positions he has held in the last 5 years, or as Vice President and Director of the Corporate and Corporate & Investment Banking segments, respectively, positions he held between 2015 and 2021.

 

The Company also informs that, under the terms of the succession plan of Santander Brasil's Senior Management, and after a favorable recommendation of the Nomination and Governance Committee, Mr. Gilson Finkelsztain was chosen to assume the position of CEO of Santander Brasil, subject to the appropriate regulatory approvals. Chief Executive Officer of B3, the executive has extensive recognition in the sector, having accumulated experience in institutions such as Citibank and J.P. Morgan, in addition to Santander Brasil itself.

 

The succession will be conducted in a transparent and organized manner and will have the direct participation of Mr. Mario Leão, who will continue to lead Santander Brasil until the conclusion of the process, scheduled for mid-2026, thus ensuring a careful and structured transition.

 

The Company will keep its shareholders and the market informed about the succession process.
